We have the technology to produce wear-resistant coatings for pipes and pipeline elements with a diameter of DN100 to DN1600 and with a length of up to 12 meters.
The inner polyurethane Puga® coating used in pipes and fittings is made by rotational or gravity casting technology into a mould.
We manufacture products which are successfully used in many strategic sectors of the economy, enabling the reduction of costs of construction and operation of pipe systems and improving the safety of their users:
Underground mining plants, including excavations at risk of explosion of coal dust and methane, and surface opencast mines:
- backfill systems,
- fire protection systems,
- hydraulic systems,
- drainage,
- air conditioning and ventilation systems,
- transport of sludge and other liquids and suspensions from processing plants,
- transmission of inert gases.
Food and beverage industry
- pipes and fittings for the transport of grains and fodder,
- systems protecting the elevators against abrasion and corrosion,
- transport systems for water-chemical treatment of agricultural crops,
- system solutions for beverage bottling plants, dairies and breweries,
- water supply systems for food processes and the discharge of post-production wastewater.
Water and wastewater industry:
- drainage systems for post-production and municipal waste landfills,
- land drainage systems,
- systems for sewage treatment plants,
- elements of settling tanks and agitators in sewage treatment plants.
Other industries:
- gas pipelines as part of the transmission infrastructure to individual and industrial customers,
- dedusting and deslagging systems in power plants,
- pipelines for alternative fuels in cement and garbage sorting plants,
- transport systems for other bulk materials.
Type of pipe connection:
- flanged according to PN-EN-1092-1 (flat and neck flanges in loose or fixed version - types 01, 11, 02 + 32, 04 + 34 with B1, E/F type sealing faces,
- sleeve (developed technology that allows welding without the risk of damage to the polyurethane surface),
- grooved (quick assembly couplings),
- threaded,
- modified (flanges adapted to the individual requirements of the investor and specific fittings such as gate valves, flow meters, etc.),
- adapter (connections of pipeline elements with various types of sealing faces).
We have the technology of integrating the seal with the inner shell and flange, which allows our pipelines to be mounted without any additional seals.
PUGA® polyurethane has a lower thermal expansion coefficient compared to other popular plastics used as internal pipeline coatings. It allows to protect steel surfaces at variable medium and ambient temperatures more effectively.
Our products meet the requirements of, among others, such standards as:
- PN-EN-1092-1 Flanges and their connections,
- ISO 2768-1 Tolerances for linear and angular dimensions,
- PN-EN ISO 8501 Preparation of steel substrates before applying paints and similar products,
- PN-EN ISO 12944 Corrosion protection of steel structures by means of protective paint systems,
- PN-EN ISO 2808 Determination of coating thickness,
- PN-EN ISO 9227 Corrosion tests in artificial atmospheres, tests in sprayed brine,
- PN-EN ISO 6270 Paints and varnishes - determination of resistance to moisture,
Industrial approvals* for:
- flame retardant and antistatic polyurethane elastomers,
- pre-insulated steel pipes and fittings with internal coating of polyurethane composite Puga® or without internal coating,
